Mid-Columbia Fire and Rescue Chief Bob Palmer says five boathouses were totaled…six more significantly damaged…and ten to eleven were saved with minimal damage from Monday night’s fire at The Dalles Marina.  Palmer says crews arrived shortly after receiving the fire call at 7:10 p.m., and found several boathouses on fire in the B finger of the Marina.  Those crews then began protecting potential exposures…battling winds that came up during the fire.  Palmer said embers from the fire ignited some nearby brush…burning an area about 300 feet long and 75 feet wide alongside Interstate 84.  Fire crews returned to that location today after reports of the brush fire restarting.  Palmer said the Port of The Dalles was able to quickly get contract crews to the Marina to contain debris and hazardous materials resulting from the boats that were damaged in the fire.  The fire is under investigation…with Oregon State Fire Marshal’s office called in to lead that work.  Palmer said one firefighter was treated for heat exhaustion at Mid-Columbia Medical Center.  Last year during the Fourth of July weekend…a fire destroyed a number of houseboats in The Dalles Marina’s D finger.
